Better Than Sex Cake

1 Devils Food cake
3/4 c. fudge topping
3/4 c. carmel topping
3/4 c. sweetened condensed milk
8 Heath candy bars
1-12 oz tub of whipped topping

Prepare Devils Food cake mix as directed by box instructions. Bake in 9x13 pan. After baking, do not remove cake from pan to let cool.  After completely cooled, using a fork, make several holes covering the top of the entire cake. Pour (one at a time) fudge, carmel, and condensed milk over the top of the cake and let each soak in before adding the next. Crush 3 of the candy bars and sprinkle on top. Frost the cake with the whipped topping and crush the remaining candy cares to decorate the top.
